Application filed November 9, 1907. Serial No. 401,403.

To all whom it may concern: v Beit known that I, DEAN H. THOMPSON, a States, residing at Fort Crook, in the county of Sarpy and State'of Nebraska, haveinvented a new/and useful Rotary Gasolene-Engine; and I do hereby declare the-following to be a full, clear, and .exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the'same.

This invention pertainsto a new, useful and novel reversible rotary gasoleneuengine; and the invention in its broadest aspect has -structed engine, o f the above type, embodying new and novel features, the arrangement of which, correlative` to one another -is after clearly manifest.

The invention, directs as a further. objectto 'provide a device of this type, comprising rotary disks, or wheels having gaschambers which operate n.piston, disposed transversely of the engine g said gas-chambers of the disks being designed to register alternately with the compression chambers, and the exhausts, as will be readily observed, in an endeavor to ascertain the operation, and the detail construction of the device. A The invention aims yas a further object tov 'provide a plurality of compression chambers,

valves, the positions of which are reversible, by a lever operating rod, so that the direction of compressed air, and gasolenev is re.- versed, that is to say, when the position .of i

reversed, as will be clearly evident'from the tion with the drawings.

A-further object of the invention dwells in the employment of a shaft, positioned transversely of the eno'ine, and to whichthe disks or wheels having the gas chambers are keyed; this shaft embodies a sleeve, having oppositely disposed eccentrics or cams, designed for the purpose of alternately operating valves or pumps for the purpose of forcing gasolene into the said compression chambers, 'as will be observed in the drawings.' These compression chambers are communicative, as shown, that is to say, each diagonally disposed compression chamberisconnected by 'a passage, as clearly illustrated in one ofthe transverse sectional views of the drawings.

p This invention comprises further objects and combinations of elements which will be hereinafter more fully described, shown in the accompanying drawings, and the novel features thereof will be appended claims.

The features and elements and the nevir pointed out by the and novel arrangement thereof, for accom-` plishing the several objects of the engine may be chan `ed and varied, that is to say, in a practica application of the construction of the device, with an understanding that the changes and variations accruing from lsaid application of the construction are limited to the scope of the appended claims.

To obtain a full and correct understandingA of the details of construction, combinations `of features, elements and advantages, reference is to be had to the hereinafter set forth description and the accompanying drawings in connection therewith, wherein- Figure l is avperspective view of the reversible rotary gasolene engine, embodying its,

Like reference characters are utilized to indicate similar features and elements throughout the several views of the accompanying drawings.

- in regard to` the accom anying drawings,

wherein similar reference c aracters indicate corres onding parts in 'thelseveral illustrations, y figures, 1 designates a suitable caserably steel, in which va shaft 2 is transversely ing, constructed of any suitable metal, pref- 85 ated, by the eccentric or cam carried bythe disposed, rin suitable bearings 3, asf cleiirly showi1;upon'each end of this shaft is keyed a .ily wheel` 4, and between the ily wheels, and the o posite faces ofthe casing, are disks or 5 whee :5, which are `keyed or otherwise fixed to rotate'with the shaft 2,' as will be clearly seen-in Fig. 2rof' the drawin s. s' f AThese disks or Wheels are ollowed out,'so

' as to provide gaschambe'rs 6, fof a'semicircu-y "purpose ofalternately registering, with the exhaust 71jand 8,:a`nd the com ression'('zham'- bers 9,- O,1`1" and 12, as wilh ereadilyobserve'dfin thedrawings; The compression vchambers 9.and 12 are 'connected-by a ,`pas

fand- 11 areconnected y a simil-ar passagef` way 14, aswillbefel'early seen in'Fig. 4 ofthe 4length equal to theidist'an'ce between the in- .nerface lof one of the'gas chamber'siof oi'ieof the or wheels, and the face of the solid' portion of the opposite disk .or wheel ;it will e noted that, b y roviding a iston at thisspecified length, t e same be reciprolcated transverselyof the engine and through the opening 30 of' the casing, which opening forms av guide forthe said piston, as willbe clearly evident. g

lValves 1-'5 and -1 6 are provided vfor co era- I the'icharges of g'ases, W ic are forced'alternately `frornfon'e compression chamber, to the f; direction, as indicated by arrows.y

IStill examining Fig. 4, it will be observed that to change the direction of the gases, the valves 15 should be closed and the' valves 16 o efrd, that is to say, when the direction of t e .charges of gasolene is, changed, solas to 'enter the compression chambers 9 and 10,

which will be hereinafter set forth. To close the valves -15 and open the valves 16, a rod or shaft 20 is mounted in bearings 21, and longitudinally of the casing of the ap aratus, which rod or shaft 20is provided wit a handie 22 by which the same is operated,jand' lugs 23 and 24, which are for the purpose of 465 coactng against the ends ofsaid vaive stems,

'lar. contour, vand which are .designed for thev y observed in lig.' 3.,.,the piston 2 9 is disposed transversely ofthe' casing, and the center thereof, and which-.piston is of -a' "tion between the passages 13 and 14 an the compression achambers, 9,' 10,. 11 and 12; thesevalves arefor the u o se of controlling' ars 19 ofthe valve 'so as to change the'positions ofthe valves 15 and 16, as clearly manifest. "The'selug's 23 and 24 are positionedupon 'a plane' at right angles to one another, as shown. Adjacent to ea'ch'enol of the sai'd rod or vshaft 20is fixed 70I a contact plate25, for the purpose of'fco'perar tion with the recessed lugs 26,1so-as .to com.-

' lete an electric circuit between the recessed ugs and s arking plugs 27, which lare'iixed to the wa ls ofthe compression chambers, 75

which sv arking plugs are connectedato aaidf yI-'ecesjse lugs by-conductors 28, as .shownin Fig. '2 in the drawings. Thesel contact plates are also pesitioned'upon a plane at j right angles to oneanothenas shown. y ,-v v Keyed lto the shaft 2v is a sleeve 31,'which provid-ed at each end'thereof withan ec-- centric or cam 32 each eccentric or cam' errf tendsina direction-opposite to thevother, for the) purpose of ,alternately operatingthel' umps 33, which force the charge of 'asoleneromthe chambers 34and 35 into't e conn pression chambers where it isignited'. l There, arefour pumps 33 andeach one comprisesa 'piston 36to which the fpiston rod 37` is con- -907 nected,the lower end offwhich isprovided" 'with' a friction roller 38, which is cooperated with b onelof the eccentrics or cams, as will befun erstood. Leading `to the' chambers 34L are the pipes 95 39, which communicate with the casing 40,A in which the oscillatoryzcylinder shaped valve 41 is positioned, which oscillatoryvalve 41 is operatedvand set, for the urposeof diey recting the flow of gasolene; w ile'the pipes `100 42 connect the chambers 3 5, with-'the c'asmg 40, as will be seen in Fig. 3 rof the drawings. lThe oscillatory valve41`is'provided with openings 43 and 44 whichlalternatefin their registrations withthe pipes 39 and. 42; thesefl'f openings" 43 and 44 are positioned upon-a p ane at right angles to one another, as clearly shown. The oscillatory valve 41 is provided with an elongated' oplening 45, which' continually registers with t e pipe46, 110 through which the gasolene flows; thls valve 41 is voperated by means' of a lever'47, as' clearly shown in Fig. 6 off' the drawings.` The pip'e 46 is provided with a valve 48, which'. is provided with: a rod connection 49 withfll governordevice 50, to which 'oneof thefly wheels 4`is Ageared by `fe"ans 'of the gear *con- 'nections 51, 52 and 53,v so as to regulatetheflow of gasolene,'whiclr-is supplied fro`m any suitable source, as desired.

` Having thus described the essential fea-- tures, elements and the correlation therebef tween, the operation 'o f the engine `is set forth, as follows.:-'-Ga'solene -is admitted into source of supply from whence it enters the chambers 35. through the check valves 54 ,'-Y the gasolene is then forced past the check valves '55,' and intotheV compression cham-" i bers z11 and 12, by ineens of the pumps 33, "130 lthe oscillatory valve 41' from any suitable 1125 that is to say, the gasolene is forced intol one, and then the other, of the compression chainbers, as will be clearly manifest at this-'stage of the operation, the gasolene in said conipression chamber 11 is ignitedf by the sparker 27, and the expansion of the gases therein acts against the piston 29, andthe wall 56 of the gas chamber 6 of tue disk or wheel 5, thus causing the disks or wheels and shaft to rotate in tne direction indicated by the arrow 57. The explosion of gasolene is als ternately repeated in first one, and tuen the other, of. the said compression chambers 11 and 12. p

Mounted upon the sleeve 81 and the shaft 2 and insulated therefrom is a sleeve 60, integral with which are Contact members 62 which project from opposite sides of thesaid sleeve 6 0,as clearly shown. lhese contact members are not in alinemeiit, but offset from each other, so as to travel in separate radii, so as to contact with the resilient contact members 61, which are secured to and l,insulated from brackets 63, upon the interior of the casing of the engine. Also sccured to one of the brackets is an additional resilient Contact member 64, which continu-- ally contacts with the said sleeve 60, as the shaft rotates, while the contact members 62 alternately contact with the members 61, so as to complete circuit for sparkingthe plugs .27 of the engine. l"he said sleeve 60 and the insulation 65 are keyed to the shaft 2 and the sleeve 31, as at '66, so as to cause them to rotate as one body, as will be clearly evident.

A suitable battery 67 is provided for furnishing current for the sparking coil 68 and the plugs 27, which battery 67` is connected electrically to the resilient contact member 64 by means of the lead 69, as. shown clearly in Fig. 5 of the drawings. ln Fig. 5 of the drawings the resilient contact members 61, 64 and the shaft 2, sleeve 31 and the sleeve 60 and its contact members 62 have been shown diagrammatically, for the -purpose of clearly illustrating the circuit for operating the sparking plugs; there being two leads 69 shown, one in full lines, which connect with the diagrammatic illustration of the contact members and the sleeve 60 and its contact members 62, and one shown in dotted lines, which is connected at the desired point, as at 70, as clearly shown. The

nected by a lead 71, in which is disposed a suitable switch 72,-the purpose of which is clearly a parent. The sparking coil 68 is electrically connected by means of a lead 7 3 with the casing of the engine, as at 7 4. Cne of the resilient contact members 61 isA connected by a lead with one of the sparking plugs 27, as at 76, Whle the other resilient contact member is connected by another sparking coil and the battery .67 are conlead 77 with another sparking plug 27, as at 7 8, as clearly shown in Fig. 5. 79 designates i a lead which connects one of the resilient f contact members and one of the sparking plugs 27, as at 80 and 8l. There are two leads 77 and 79 illustrated, one of each being shown in full lines and dotted lines', as at 82 and 83. Connected as at Slis a lead which is also connected, as at 86, to one of the sparking plugs 27, there .being twoof these' leads 85 shown, one in full lines and one in dotted lines, as at 87. il"here are also two leads 7 5 illustrated, one in Vfull lines and one in dotted lines, as at 88, as clearly illustrated in Fig. 5. 5

The operation of the sparking plugs and the contacts 61 and land the sleeve 60 and the contacts 62 and the ow of the current is set forth as follows When one of the con-` `tacts 62 is in engagement with one of the resilient contacts 61, as shown clearly in the diagrammatic illustrations of this feature, current leaves the battery through the lead 69 to the sleeve 66', through the resilient contact plate 64, thence the current advances through one of the contacts 62 and the contact 61, as seen in Fig. 5, t'o one of the sparking plugs 27, through the lead 85, as als(` seen in Fig. 5. Ilhe current at this point continues through the lead 28, to one of the lugs 26 through the shaft'20 to the connection of the lead 73, as seen at 74 from this point the current forwards through the lead 73 back to the battery, through the sparking coil 68, switch 72 and thelead 71, so as 'to spark the plug, as seen at 27 a, as will be clearly observed: When the other contact point 62,

as seen at ct in TEig. 5, engages the other re- .passes through one of the contacts 62, through one of the contact plates 61, to a point indicated by the reference character b. From the point, as seen'at 27 b, thel current passes to one of the lugs 26, as at c, thence through the lead 73 back to the battery, through the sparking coil 68, the switch 72 and the lead 71, as will be clearly manifest.

To reverse the i'low of current, so as the other sparking plug 27 will be operated, the shaft 20 is given a slight rotation, so as to change the position of the oppositely disposed contact plates 25, whereby the cul"- rent will, enter the shaft 20, as seen at 20a, in which case the direction of the flow of current will be readily apparent, in an endeavor to trace the same through the various leads and contact points. First one and then another of the sparking plugs 27 are operated, so as to ignite the charge in the compression chambers 9, as will be clearly evident.

It be plainly manifest that by reversing the positions of the valves and 16, and

by changing the, position' of the valve 4Lil, a

, reverse rotary motion Willbe imparted to the disks or Wheels 5. I The utilized gase'smerge l 5 into one exhaust 58, as shown.'

From the foregoing, he essential'feat'ures, elements and the operation of the'device, togetherfvvith the sim licity thereof, will be clearly apparent;` an

1 0 place; the now vcumbersome engines used, viz.-reversible gears and a reat amount ,of heretofore Wasted energy Wi be saved.4
